A lot of the fundamental issues with MCP are still present: MCP is pretty single-player, users must "pull" content from the service, and the model of "enabling connections" is fairly unintuitive compared to "opening an app."
Ideally apps would have a dedicated entry point, be able to push content to users, and have some persistence in the UI. And really the primary interface should be HTML, not chat.
As such I think this current iteration will turn out a lot like GPT's.
